Garee Bonez How to lock down the Ulna?

Jayfeather

Untill we have a Genesis Skeleton, Garee's Bonez addon for the Mil3 Skeletons seems to be the most versitile,  The only problem is the Ulna's seem to have a mind of their own when it comes to animation, and I don't see any adjustments that deal with this behavior.  Anyone got an experiance dealing with this issue?
